Steps to reproduce:

1. Open attached project;
2. Click on "Main Camera" GameObject;
3. In the Scene view mark "Occlusion culling" checkbox;
4. Check "Camera Volumes", "Visibility Lines" and "Portals" flags;
5. Observe the Scene View Occlusion Culling visualization.

Actual result:
Scene filters (Camera Volumes, Visibility Lines and Portals) are not applied to the Scene view (see attached actual.png file).

Expected result:
Scene filters (Camera Volumes, Visibility Lines and Portals) should be correspondingly displayed, when "Occlusion culling" checkbox is marked (see attached expected.png file).

Regression from: 4.6.5f1.
